You can, of course, find some statistics with a web search. But much of the data you need will be deep within a database file structure, and hidden from search engines.
For better results, search the data sources, directly.
The library links you to the online and print sources purchased by the library and to the data sources often buried within the sites of major statistical organizations (World Bank, IMF, Eurostat, UN, and many more).
